There are many more potential refuges including Mars, Asteroids, Orbital colonies, Venus clouds, but also more pedestrian options like under the sea (with power coming from geothermal vents)
By the time we have self-sufficent colonies that can survive the loss of Earth, we'll have the ability and understanding to prevent the eruption anyway.
Mars is too far to use as the primary refuge planet. Asteroids are the very last option. Venus wouldn't even be on the table due to the proximity to the Sun. Submerged colonies might work, but with all of the ash sinking into the water and becoming a sludge, I think the filters on the submerged habitats would become clogged very quickly.
Orbital stations would work, but considering the eruptoce force of the Super V erupting, orbital colonies might get knocked out of orbit.
One way to save a lot of human life would be to develop cryogenic stasis systems that would keep people in suspended animation for upto 300 years.
The Cryo Units would be placed on the dark side of the Moon, away from any potential debris from the Earth that might collide with the Moon.
Mars would be the secondary refuge planet to store seeds and people in cryo units on just in case something went wrong on the Moon.
500,000 million cryo units on the Moon and 10,000 on Mars, would ensure diversity was maintained along with having enough people to begin digging out the Earth from under fallout of the Super V.
Then again the eruption might cause the Moon's orbit to destabilize and cause it to come closer to or be pushed further away from the Earth.
One exciting potential that could aria is the Moon might trap some on the ejecta from the eruption that could be collected and processed by the colonies on the Moon.
Based on the documentary I watched, the surface of the Earth will look similar to the surface of the Moon, in so much that gray ash will cover all of the U.S., Canada and South America, with the rest of the world seeing maybe a half foot of ashen fallout.
When the Earth does recover from the Super V eruption, the landscape will be entirely different. Most of the ashen fallout should become swamp like due to rains. As the swamps dry up, Trees and plants life should begin to break through the hard layers of ash and solidified lava.
Who knows, maybe even life forms will emerge, just like new life emerged after the rock that killed the dinos off collided with the Earth, a scant example of what the Super Volcano under Yellowstone will be like when it does finally erupt.
The Titanic comes to mind when I think about the Super V erupting. We know it's coming, we need to start adjusting course now so that when Super V does go up, all we will hear is a slight rubbing of the hull against the eruption instead of a sudden and full decompression of the human race.
